Odoo 18 to Odoo 20 migration — skip a version, keep your code and your data.
Standard support for Odoo 18 is planned to end in September 2027. Moving straight to Odoo 20 gives you the longest runway: we rebuild your modules for the new version and migrate your data with zero loss.

What changes from Odoo 18 to 20
An upgrade isn’t a copy-paste. Here’s what actually has to be done — and what we handle for you.
Two versions of changes handled in one project — no stop at Odoo 19.
Access-rights changes in Odoo 20 — custom security rules are checked and adapted.
Field Service is now part of Planning — reports, automations and dispatch flows move to Planning shifts.
Accounting renames (payment statuses, parent accounts) — custom reports and filters updated.
Integrations on the older external API checked, with a plan for the newer JSON-2 API.
Your code and your data — both move
Most migrations only move your data and leave your customizations behind. We do both: your custom modules are rebuilt for Odoo 20, your full history is migrated and validated, and nothing goes live until you’ve signed off. Community or Enterprise, on-prem or odoo.sh.
Validated, record by record
Your database migration is checked at the record level with a full audit trail from source to target. Customers, invoices, transactions and history are reconciled against the original — no orphaned references, no dropped records. If a number doesn’t match, it doesn’t go live.

Migration questions, answered
Yes. We migrate you to Odoo 20 in one project — you don’t need to stop at Odoo 19. We handle the upgrade scripts and module changes for both versions.
Odoo’s planned end of standard support for Odoo 18 is September 2027. Planning your upgrade in the next few months leaves time to test without pressure.
Odoo 20 gives you the longest support runway. Choose Odoo 19 if an app or custom module you depend on isn’t ready for Odoo 20 yet — the free audit checks this for you.
No. Every record is migrated and validated against the source, and nothing goes live until you’ve reviewed it.
We rebuild and test your customizations for Odoo 20 rather than dropping them — including security rules, reports and views affected by the new version.
It depends on the size of your database, how many custom modules need rebuilding, and which apps and integrations you use. After a free migration audit we give you a fixed quote, so the price doesn’t grow during the project. Odoo license fees are separate — see Odoo pricing.
